Day 130: Whiteboarding, Problems, & Lab

AP Physics 1: Whiteboarding

We did some whiteboarding of last week’s torque problems. Students aren’t confident, but they are getting the hang of extended free-body diagrams and successfully solving problems. With the clock ticking, that will have to be good enough for balanced torques.

Physics: Problems

Students did some problems with standing waves. It was tricky for a lot of them to connect the wavelength to the length of the resonator, so that will be something to work on during whiteboarding tomorrow.

Chemistry Essentials: Lab

Students did a lab with magnesium and hydrochloric acid. We stuck with purely qualitative observations today and will get into the actual stoich tomorrow.
